| Research Abstract |
About wood and paper yarn, the static fracture phenomenon was solved using percolation. In the model, the fracture phenomenon was clarified by catching a fracture phenomenon probabilistically, introducing the concept of the dangerous element based on local material strength, and describing the damage accumulative process and fracture intensity in static destruction in Monte Carlo simulation. As a result, static destruction of wood and paper yarn discovered that the latter could be described by percolation.
